Miami Heat forward Chris Bosh has acknowledged the latest setback in his attempt to return from a pair of season-ending bouts with blood clots, while not necessarily giving up hope of returning to the NBA.

In the wake of the Heat announcing that Bosh had failed his preseason physical, the All-Star power forward released a video statement about his status, one that focused on his plans to continue with his pre-taped documentary series on his offseason work to get back on the court.

Bosh's video was accompanied by a Twitter post of, "Setbacks may happen, but my intentions remain the same. Thank you all for the warm wishes and support."

Bosh, who received a second opinion from the NBA that agreed with the Heat's findings, did not make any definitive declaration about the direction of his career.

"That doesn't stop me from wanting to share my creative side with you guys and hoping that you want to come along on the journey with me," he said of his failed physical in his video post. "So, just because the journey has ups and downs doesn't mean that I will stop sharing with you guys. So I will just continue to share, despite what's going on.

"Little setbacks happen, but that doesn't change my intentions and what I want accomplish. So, I hope you continue to watch. I hope you continue to really just take in my journey and just come along with me, with the ups and the downs. So it's a down moment right now, but everything's going to be all right."

With that, Bosh went ahead with the online release of the second chapter of his documentary "Rebuilt" that is featured on the LeBron James-operated digital outlet Uninterrupted, a chapter titled "Renewal."

Among the references in Bosh's documentaries have been ones to former Florida Panthers forward Tomas Fleischmann, who has pushed past similar issues with blood clotting to return to the NHL. On Friday, however, Fleischmann failed his physical amid a tryout with the Minnesota Wild, leaving his career in doubt, as well.

Bosh's latest documentary installment was updated to include the statement, "On the eve of the 2016-17 season, the Miami Heat have not cleared Chris to play. It is Chris' hope that he can return to playing basketball."

During the episode, Bosh documented the steps he took in the offseason to make what he believed would be a return to training camp, which for the Heat opens Tuesday in the Bahamas after Monday's media day at AmericanAirlines Arena.

Bosh remains on the Heat roster and is likely continue to do so for the foreseeable future. He will be paid the entire $76 million remaining on the final three years of his contract, with insurance likely to kick in to absorb half that amount.

The earliest Bosh's salary can be removed from the Heat's salary cap would be Feb. 9, the one-year anniversary from his most recent game. However, unless Bosh formally retires, the Heat's ability to shed his salary-cap hit will remain in question.

Bosh's latest video chapter opens with him narrating, "Sometimes you just have to be broken down to rebuild yourself and come back better than ever."

In the episode he reveals that part of his experimentation during the offseason included going off the blood thinners prescribed to avoid a recurrence of clotting.

"We began to do our own research," he said. "We began to find articles. We began to find papers. We began to find other doctors, who were not only forward thinking but were specialists who could help, who dealt with athletes before, so we decided to get smarter.

"The doctors that I work with, it's more so just a matter of procedure. We have the formula. They take the blood, they study it: on blood thinners, off blood thinners. And they get all the data possible to put their formula into it and customize it for me."

Bosh then offered the optimism he carried into his Heat physical, one conducted earlier this week.

"So it wasn't a matter of if I'm going to play again, but when," he said. "I can still play the game."
